WIRE-BARBING MACHINE.

SPECIFICATION forming part of Letters Patent No. 298,131, dated May 6,1884.

Application filed May 9, 1883. (No model.)

To all 1127710170711 may concern.-

Be it known that I, DANIEL G. STovER, a resident of Freeport, in thecounty of Stephenson and State of Illinois, have invented certain newand useful Improvements in Wire- Barbing Machines; and I do herebydeclare the following to be a full, clear, and exact de scription of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same.

My invention is an improved machine for attaching certain forms of wirebarbs to twostrand fence-cables. Its details are fully described in thefollowing specification and shown in the accompanying drawings, inwhich- Figure 1 is a plan of the machine; Fig. 2, a front elevationthereof; Fig. 3, a side elevation of the barb-forming sleeve andspindle, with bearings and gearing; Figs. 6, 5, and 4c, perspectiveviews of the stationary spindle Q, the sleeve 0, which rotates thereon,and the hook-carrying collar N, Which turns with said sleeve; Figs. 7,8, and 9, front elevations of the spindle, sleeve, and collar in theirsuccessive positions in the formation of a barb; Fig. 10, a horizontalprojection of the same parts in the position shown in front elevation inFig. 8; Fig. 11, a horizontal projection of the same parts in theposition shown in front elevation in Fig. 7 and Fig. 12, a frontelevation of the forked lever E, which imparts longitudinal motion tothe collar- N.

In these views, A is the bed of the machine, 13 its driving-shaft, and Ba side shaft connected with the driving-shaft by miter-gears. The shaftB carries two rigidly-mounted cams, G O, the first of which impartsreciprocal rotary motion in a vertical plane to the segmental gear X,while the second imparts vibratory motion in a horizontal plane to theforked lever E. The segment X moves about the shaft F as an axis, andthe lever E swings about a pivot in the vertex of the post F as acenter.

Near the center of the bed, and in a line parallel to the side shaft, B,are rigidly attached to the bed two vertical posts, H H, in which isjournaled near the face of the bed the horizontal shaft G. A pinion, I,is rigidly mounted on the shaft G between the posts H H, and a secondand larger pinion, I, is rigidlymounted on said shaft in front of thepost H.

Above the pinionI is a horizontal spindle, Q, formed integrally with thepost H, or rigidly attached to its face, both post and spindle beinglongitudinally perforated for the passage of two main wires to bebarbed. On the spindle Q rotates freely a sleeve, 0, on which is rigidlymounted a pinion, I, which engages with the pinion I immediately belowit, and on the sleeve 0 is a collar, N, attached to the sleeve by meansof a key, which per; mits longitudinal motion of the collar on thesleeve, but not rotary motion. A groove, L, is cut in the peripheryofthe collar, and in this groove lie the ends of the fork J at theinner, end of the lever E; At the front end of the collar N is a radialhook, K, extending inward toward the center, and provided at its innerend with a horizontal wrapping-pin, 1", extending from the hook towardthe plane of the face of the collar, the distance from the end of thewrapping-pin to the plane of the face being not less than the thicknessof the barbing-wire.

From the drawings and the foregoing explanation it is plain that therotation of the driving-shaft, shaft B, and cams G C will producereciprocal rotary motion of the sleeve 0 and reciprocal longitudinalmotion of the collar N on the sleeve, and that, whatever of the face ofthe sleeve and spindle, the free end S of the barb-wire lyingimmediately under the hook K, as shown in Fig. 7, and the collar N beingdrawn back on the sleeve 0, so that the end of the wrapping-pin P restsagainst the face of the sleeve, as shown in Fig. 11. The sleeve O,withthe collar N and pin 1 is then rotated in the direction indicated by thearrow in Fig. 7 through an angular space of four hundred and fiftydegrees, or one and onefourth revolution, until the hook reaches theposition shown by the dotted lines in Fi 8 and the barb assumes the formshown in Fig. 8. The barb is then severed and the sleeve rotated in thedirection indicated by the arrow in Fig. 8 until it reaches the end B ofthebarb, the collar being at the same time moved forward on the sleeveuntil their faces are flush and there is a distance between the end ofthe wrapping-pin and the face of the sleeve equal to the diameter of thebarbing-wire. This brings the parts into the position shown in Fig. 10,when a further rotation of the sleeve in the direction indicated by thearrow in Fig. 8 through an angle of two hundred and seventy degreescarries the end B- into the position shown in Fig. 9 and completes thebarb. In making the last wrap, the hook K passes around the point S ofthe barb, the space between the end of the wrapping-pin and the face ofthe spi ndle being sufficient to permitthe end R to pass through it, asthe end ofthe barb lies in close contact with the face of the sleeve.

It is evident that the hook K need not necessarily be attached to acollar encircling the sleeve 0, but may be attached to the sleeve in anyother way that will allow it longitudinal but not rotary motionindependent of the motion of the sleeve-as, for instance, by forming thehook with a straight shank of polygonal form sliding in a correspondinggroove in the sleeve-and that various devices may be employed to give itlongitudinal motion.

The hook K, as shown and described, is provided witha wrapping-pin, I,extending from the end of the hook inward toward the face of the sleeve0. This wrapping-pin may, however, be dispensed with by giving the hooksufficient thickness to afford a proper bearing-surface for wrapping thebarb.

No novelty is claimed for the devices used to rotate the barb-formingparts of this machine, as the cams and gearing shown are old andwell-known mechanical expedients.

Having, however, described my invention and explained its operation,what I claim as new, and desire to secure by Letters Patent, is-- 1. Ina wire-barbing machine, the combination of a spindle perforatedlongitudinally for the passage of the main wires, a sleeve rotatingfreely on saidspindle, and a barb-wrapping hook attached to and rotatingin unison with said sleeve, but having longitudinal motion independentthereof, whereby it is adapted to wrap one of the ends of abarbin a coilarranged next to the face of the sleeve and spindle, and the other endin a second coil continuous with the first, but arranged farther fromsaid face.

2. In a wire-barbing machine, the combination of a spindlelongitudinally perforated for the passage of the main wires, a sleeverotating freely on said spindle, a collar encircling said sleeve androtating therewith, buthaving longitudinal motion independent thereof, abarb-wrapping hook rigidly attached to said collar, and adapted to wrapone end of a barb in a coil arranged next to the face of the spindle,and. the other endin asecond coil continuous with the first, butarranged farther from the face of the spindle, and means for impartingreciprocal longitudinal motion to said collar.

3. The combination of the longitudinallyperforated spindle Q, the sleeve0, rotating thereon, the collar N, keyed to said sleeve and rotatingtherewith, but free to move longitudinally thereon, the hook K, rigidlyattached to said collar, the forked lever E, engaging with the annulargroove Lin the collar 1\*,and means for imparting reciprocal motion tosaid lever, whereby reciprocal longitudinal motion is imparted to saidcollar, substantially as shown and described, and for the purpose setforth. In testimony whereof I have signed this specification in thepresence oftwo subscribing witnesses.
